Sony (Konica / Minolta) DSLR Only

This is the fourth in a series of "xxx DSLR only" challenges. It took some time before the public wouldn't only link this brand name to Walkmans, but DSLRs also. After all, audio equipment was Sony's field of expertise and few consumers were aware of their steadily advancing sensor technology. Dear Sonyites, your challenge theme is, of course, "Music". Have fun!
